# Section 309 Haze Planning Support - Select A Forum Destination -

What is Section 309?

Section 309 of the RHR includes a provision that recognizes the work of the Grand Canyon Visibility Transport Commission, which addresses regional haze impacts within 16 western Class I areas on the Colorado Plateau. This section of the rule offe rs an early “opt-in” for regional haze planning by the States and Tribes in the GCVTC region

. Compliance with the reasonable progress requirements of the ru le is achieved by including the recommendations already developed by the GCVTC, In addition, “Best Available Retrofit Technology” (BART) must be included on specific categories of major stationary sources of haze-producing pollutants, primarily existing el ectrical generating units (EGUs) that emit large quantities of SO2 and NOx. The States of Arizona, New Mexico, Oregon, Utah, and Wyoming opted into this provision and submitted complete §309 regional haze plans to their respective EPA regional offices by the deadline of December 2003. Oregon has since decided to address regional haze planning through §308 of the RHR. Bernalillo County (Albuquerque) has air quality planning responsibilities in that portion of New Mexico and has submitted its §309 regional haze plan independently.

Since the 2003 submittals the §309 states have been successfully implementing the GCVTC recommendations along with other measures contained in the plans. These include documented SO2 reductions far in excess of those anticipated in the submitted plans, BART determinations, activ e smoke management

The Western Regional Air Partnership has been working closely through its various committees and forums to provide background data and support for preparation of Section 309 state implementation plans. A complete list of those documents is provided listed below. Other states and tribes have participated in developing these materials and may choose to use elements of the Section 309 plans to template in developing their own plans due in the next few years.

Results indicate that the 2005- 2007 average emissions were about 33% below the revised 2007 milestone for the four §309 states.

§309 Program Materials (April ‘08 Final Revisions) Four western states (AZ, NM, UT & WY) are planning on re-submitting State Implementation Plans under Section §309 of the federal regional haze rule. These states (along with OR) originally submitted SIP’s in 2003, but due to legal challenges, these initial submittals were never approved by the EPA. The four remaining §309 states began working on redesigning the SO2 Milestones required for the §309 Regional Haze option in early 2007, and have now developed a proposal for revised Milestones, along with a variety of s upporting materials for

FINAL REPORT: WRAP SO2 MILESTONE TRACKING PROCESS AUDIT (10/02/07) PDF Five western states (AZ, NM, OR, UT & WY) submitted State Implementation Plans under Section §309 of the federal regional haze rule [40 CFR 51.309] to establish a sulfur dioxide (SO2) milestones and a backstop trading program. This program requires major

1/6/2011 file://H:\6PD\6PD-L\NM SIP- FIP Docket\Echo of NMED web site as of 12-21-10\309.htmindustrial sources of SO2 emissions to submit an annual emissions inventory to their respective state air quality offices. These inventories, in turn, are compiled by the Western Regional Air Partnership (WRAP) and analyzed to determine compliance with the regional SO2 milestones.

The backstop trading program also calls for an independent audit to ensure that the state inventories and regional analyses are accurate and efficient. The program guideline states that the first audit shall occur during the 2006 calendar year, and shall review data collected during the first two years of the program. The primary focus of the audit is on the process that is used to compute the regional inventory from the data provided by each state, and the tracking of accumulated changes during the period between SIP revisions. The audit shall also review the accuracy and integrity of the regional reports that are used by the §309 states to determine compliance with the milestones.

This document represents the FINAL Report, describing the results of the milestone tracking program audit that was conducted by E.H. Pechan & Associates during the Fall of 2006. The participating §309 States completed Public Notice of this report during the Spring/Summer of 2007 to provide an opportunity for public review and comment on the draft audit report. The audit report then goes to the EPA under each stat es’ Administrative
process.

The original "Version 1" of the Point Source Database wa s compiled by Pacific Environmental Services in 2001 (the PES Report on this database compilation can be found listed as the "Final Report: Development of the 1996 Base Year Emissions Inventory for Regional Haze Analysis " file available on the

" Documents " page under the "WRAP Base Year Emissions Inventory" section of the Emission Forum Webpage).

A Quality Assurance review of "Version 1" revealed a number of data errors, therefore the Emission Forum contracted with E.H. Pechan and Associates to revise this 1996 Point Source database file to correct those detected errors. Pechan produced "Version 2" of the database in the Fall of 2002, which underwent thorough State and Local review. This State & Local review produced significant comment, which Pechan addressed by producing the March 11, 2003 updated "Version 3" of this database (listed as the

" WRAP96PointV3_022803.zip " file available below).

The changes that were made to the original 1996 Point Source database by both the "Version 2" and the "Version 3" revisions were described in a March 7, 2003 "Technical Memorandum" (listed as the " 2003

- 03_Pechan TECHMEMO.wpd " file available on the " EI Documents " page under the "Quality Assurance Review of the Original 1996 Point Source Emission Inventory" section of the Emission Forum Webpage).

Development of WRAP Mobile Source Emissions Inventories PDF (02/09/04) On behalf of the Emissions Forum, ENVIRON Corporation has developed approaches for estimated mobile source emissions across the contiguous WRAP region, used in the §309 analyses. Projecting emissions from 1996 through 2018, this report describes in detail the methods used to estimate mobile source emissions, and provides the resulting emissions estimates. Emissions in this mobile sources inventory include on-road and off-road vehicles and engines, and though typically not considered part of mobile sources, road dust emissions estimates are also described in this report.

Fire Sources 

## Wildfire, Prescribed (Rx) Wildland Fire and Agricultural Fire Emissions Inventories

The spreadsheets below contain summaries of the WRAP States "Wildfire", "Prescribed (Rx) Wildland Fire" and "Agricultural Fire" Emissions Inventories that have been compiled by the Fire Emissions Joint Forum (FEJF), 

### Page 13 of 17 Section 309 Planning Support

1/6/2011 file://H:\6PD\6PD-L\NM SIP- FIP Docket\Echo of NMED web site as of 12-21-10\309.htmfor the years, 1996 and 2018.

The Emissions Inventories are compiled for seven regional haze pollutantsincluding: VOC's, NOx, CO, SO2, PM10, PM-2.5, and NH3.

Each EXCEL spreadsheet file listed below contains two individual data sheets, followed by graphs of the distribution of the emissions throughout the WRAP region.

Sheets #1 & #2 of each spreadsheet file summarize emissions data. Sheet one summarizes the data by state, for each of the 13 contiguous WRAP States (with a separate subtotal of the emissions generated by the 9 GCVTC transport region states). Sheet two summarizes emissions by county, for each of the 533 counties in those 13 WRAP States where the FEJF determined that fire occurs (if a county is not listed, that means that the FEJF has found no fire emissions for that category in the county).

Sheets #4 through #17 of each spreadsheet file provide graphs of the emissions data. For each of the seven listed pollutants, there is both a "Bar Chart" and a "Pie Chart" showing the distribution of the emissions of that pollutant in the 13 WRAP States.

For 1996, the FEJF calculated an emission inventory for the "actual" wildfire activity that occurred that year. The FEJF also calculated an emi ssion inventory for actual Prescribed (Rx) Wildland Fire in 1996, but they were unable to compile any data for 1996 Agricultural Fire, so there is no 1996 inventory for Agricultural Fire. The 1996 spreadsheets include:

z 1996_wildfire_sum.xls

z 1996_rx_sum.xls

For 2018, the FEJF calculated an emission inventory for the "average" wildfire activity that historically has occurred (as 1996 was considered an extreme wildfire 

### Page 14 of 17 Section 309 Planning Support

1/6/2011 file://H:\6PD\6PD-L\NM SIP- FIP Docket\Echo of NMED web site as of 12-21-10\309.htmyear). The 2018 wildfire spreadsheet is:

z 2018_wildfire_sum.xls

Regarding 2018 projections for Prescribed (Rx) Wildland Fire and for Agricultural Fire, the FEJF calculated three scenarios for each of these two categories; a "Base Year" emission inventory, a "No Smoke Mangement" alternative, and an "Optimal Smoke Mangement" alternative alternative. The 2018 spreadsheets include:

z 2018_rxbase_sum.xls

WRAP Region Combined Categories Summaries

The files below contain summaries of a complete WRAP Region Emission Inventory (13 contiguous WRAP states include: AZ, CA, CO, ID, MT, NV, NM, ND, OR, SD, UT, WA & WY).

The summaries are compiled for all Seven Visibility Impairing Pollutants (VOC, NOx, CO, SO2, PM10, PM2.5 & NH3), for the years 1996 and 2018.

The Nine Emission Source Categories include:

z point sources

z area sources

z on-road mobile sources

z non-road mobile sources

z wildfire

z prescribed wildlands fire (Rx)

z agricultural fire

z paved road dust (PM only)

z unpaved road dust (PM only)

1/6/2011 file://H:\6PD\6PD-L\NM SIP- FIP Docket\Echo of NMED web site as of 12-21-10\309.htmThe first page of each spreadsheet contains a "Summary" of the emissions from each of the sour ce categories, their percentage of the WRAP region total and the year's tonnage for each pollutant. The second page contains the "State Totals" of each Source Category, for each pollutant.

Sheets #3 through #16 of each spreadsheet file provide graphs of the emissions data. For each of the seven listed pollutants, there is both a "Bar Chart" and a "Pie Chart" showing the distribution of the emissions of that pollutant in the 9 Emission Source Categories.

For 1996, the EXCEL spreadsheet "1996_Summary-Actual.xls" contains actual emissions data compiled by the WRAP. There was no "Agricultural Fire" data available for 1996 however, so that category is shown as "zero" on the spreadsheet, when in actuality there likely were emissions from this source category that year.

z 1996 Summary

- Actual.xls

For 2018, the EXCEL spreadsheet "2018_Summary-Control .xls" contains maximum controlled emission data as projected from the 1996 baseline. There were four source categories where projected emission inventories were compiled for multiple scenarios. These include "point" sources and the three "fire" sources (wildfire, Rx & ag). For the point sources, the scenario represented in this spreadsheet represents the Annex SO2 Emission Milestones. For 2018 wildfire, the scenario selected is an "average" wildfire year (1996 represented a high extreme). For the other two fire sources (Rx & Ag), the selected option represents the "Optimal Smoke Management" scenario.
